KDP결정을 이용한 고강도 Nd 레이저광의 제4 고조파변환 해석
Analysis of Fourth Harmonic Conversion of High Intensity Nd Laser Beam in KDP Crystal
초록
The fourth harmonic conversion(FHC) efficiency of high-power Nd laser pulse with wavelength of 1.054x10S0-6Tm using two KDP crystals(doubler adn quadrupler) was simulated numerically. Simulation results show that for the perfect phase-matching condition the FHC efficiency were 60-70% for several hundreds MW/cmS02T class and over 70% for GW/cmS02T class laser pulses. And the overall characteristics of FHC were discussed in terms of effects of input intensity, crystal length, and mismatch angle Δ
